Larger-Volume Silicone Breast Implants Are Safe in Breast Reconstruction: The Athena Multicenter Prospective Study of 400 Patients.
Trial report in Plastic and reconstructive surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFor women in the United States desiring implant-based breast reconstruction, the maximum volume of commercially available silicone breast implants has, to date, been 800 cc. The authors evaluated the safety of Mentor larger-size MemoryGel Ultra-High Profile breast implants (≥930 cc) in women undergoing postmastectomy breast reconstruction.
methodsThis 10-year, multicenter, open-label, prospective, investigational study assessed the safety and effectiveness of larger-volume implants in women undergoing postmastectomy 2-stage primary or revision reconstruction. Three-year Kaplan-Meier curves and multivariable Cox regression analyzed the association between patient and treatment characteristics and surgical outcomes. The BREAST-Q was used to assess effectiveness at 3 years.
resultsA total of 400 women were enrolled (225 primary and 175 revision reconstruction). Mean body mass index was 35.8 kg/m 2 ; 81% had a body mass index greater than or equal to 30 kg/m 2 . At 3 years, the cumulative incidence of postoperative complications (excluding rupture) was 63.0% (95% confidence interval, 58.1% to 67.9%). The reoperation rate was 24.5% (95% CI, 20.4% to 29.1%), and the explantation rate was 15.8% (95% CI, 23.5% to 19.9%). Independent predictors of complications included radiation therapy and a history of smoking. There were no significant associations between postoperative complications and implant volume greater than or equal to 1135 cc or less than 1135 cc. BREAST-Q scores at year 3 showed significant improvements from baseline in Satisfaction with Breasts, Psychosocial Well-Being, Sexual Well-Being, and Physical Well-Being (all P < 0.0001). The mean score for Satisfaction with Outcome was 79.9.
conclusionsThese 3-year results demonstrate that larger-volume silicone breast implants represent a safe and effective option for patients with larger breasts who are requesting postmastectomy implant-based reconstruction.
